Parsel is a library to extract data from HTML and XML using XPath and CSS selectors
* Free software: BSD license
* Documentation: https://parsel.readthedocs.org.
Features
--------
* Extract text using CSS or XPath selectors
* Regular expression helper methods
Example::
>>> from parsel import Selector
>>> sel = Selector(text=u"""<html>
<body>
<h1>Hello, Parsel!</h1>
<ul>
<li><a href="http://example.com">Link 1</a></li>
<li><a href="http://scrapy.org">Link 2</a></li>
</ul
</body>
</html>""")
>>>
>>> sel.css('h1::text').extract_first()
u'Hello, Parsel!'
>>>
>>> sel.css('h1::text').re('\w+')
[u'Hello', u'Parsel']
>>>
>>> for e in sel.css('ul > li'):
print(e.xpath('.//a/@href').extract_first())

History
-------
1.4.0 (2018-02-08)
~~~~~~~~~~~~~~~~~~
* ``Selector`` and ``SelectorList`` can't be pickled because
pickling/unpickling doesn't work for ``lxml.html.HtmlElement``;
parsel now raises TypeError explicitly instead of allowing pickle to
silently produce wrong output. This is technically backwards-incompatible
if you're using Python < 3.6.
1.3.1 (2017-12-28)
~~~~~~~~~~~~~~~~~~
* Fix artifact uploads to pypi.
1.3.0 (2017-12-28)
~~~~~~~~~~~~~~~~~~
* ``has-class`` XPath extension function;
* ``parsel.xpathfuncs.set_xpathfunc`` is a simplified way to register
XPath extensions;
* ``Selector.remove_namespaces`` now removes namespace declarations;
* Python 3.3 support is dropped;
* ``make htmlview`` command for easier Parsel docs development.
* CI: PyPy installation is fixed; parsel now runs tests for PyPy3 as well.
1.2.0 (2017-05-17)
~~~~~~~~~~~~~~~~~~
* Add ``SelectorList.get`` and ``SelectorList.getall``
methods as aliases for ``SelectorList.extract_first``
and ``SelectorList.extract`` respectively
* Add default value parameter to ``SelectorList.re_first`` method
* Add ``Selector.re_first`` method
* Add ``replace_entities`` argument on ``.re()`` and ``.re_first()``
to turn off replacing of character entity references
* Bug fix: detect ``None`` result from lxml parsing and fallback with an empty document
* Rearrange XML/HTML examples in the selectors usage docs
* Travis CI:
* Test against Python 3.6
* Test against PyPy using "Portable PyPy for Linux" distribution
1.1.0 (2016-11-22)
~~~~~~~~~~~~~~~~~~
* Change default HTML parser to `lxml.html.HTMLParser <http://lxml.de/api/lxml.html.HTMLParser-class.html>`_,
which makes easier to use some HTML specific features
* Add css2xpath function to translate CSS to XPath
* Add support for ad-hoc namespaces declarations
* Add support for XPath variables
* Documentation improvements and updates
1.0.3 (2016-07-29)
~~~~~~~~~~~~~~~~~~
* Add BSD-3-Clause license file
* Re-enable PyPy tests
* Integrate py.test runs with setuptools (needed for Debian packaging)
* Changelog is now called ``NEWS``
1.0.2 (2016-04-26)
~~~~~~~~~~~~~~~~~~
* Fix bug in exception handling causing original traceback to be lost
* Added docstrings and other doc fixes
1.0.1 (2015-08-24)
~~~~~~~~~~~~~~~~~~
* Updated PyPI classifiers
* Added docstrings for csstranslator module and other doc fixes
1.0.0 (2015-08-22)
~~~~~~~~~~~~~~~~~~
* Documentation fixes
0.9.6 (2015-08-14)
~~~~~~~~~~~~~~~~~~
* Updated documentation
* Extended test coverage
0.9.5 (2015-08-11)
~~~~~~~~~~~~~~~~~~
* Support for extending SelectorList
0.9.4 (2015-08-10)
~~~~~~~~~~~~~~~~~~
* Try workaround for travis-ci/dpl#253
0.9.3 (2015-08-07)
~~~~~~~~~~~~~~~~~~
* Add base_url argument
0.9.2 (2015-08-07)
~~~~~~~~~~~~~~~~~~
* Rename module unified -> selector and promoted root attribute
* Add create_root_node function
0.9.1 (2015-08-04)
~~~~~~~~~~~~~~~~~~
* Setup Sphinx build and docs structure
* Build universal wheels
* Rename some leftovers from package extraction
0.9.0 (2015-07-30)
~~~~~~~~~~~~~~~~~~
* First release on PyPI.
